Peak wavelength temperature equation

WebThe total power radiated by a blackbody is given by the Stefan-Boltzmann equation, but it is often interesting to know the fraction of power which is emitted in the visible or some other wavelength range.. Temperature T = K = °C Area A = cm 2 = x10^ m 2 Emissivity = (e = 1 for ideal radiator) The total power radiated is P = watts = x10^ watts. Finding the power …
